Temperatures will be cooler through the end of the week then warm again this weekend. Overnight and morning low clouds and fog will develop along much of the coast and into some adjacent valleys through the week.
Temperatures warmed up several degrees inland Tuesday due to strong high pressure aloft and light offshore flow. However that influence was negligible at the coast where a cool sea breeze kept temps much cooler and near average.
Wednesday we will have high cloud cover as well as a marine layer along the coast. Temperatures will cool a couple degrees primarily in the upper 60s at the coast and in the mid 70s in the valleys.
Wednesday night into Thursday those high clouds are expected to thicken up quite a bit and keep skies mostly cloudy. Between that
and the cooling aloft associated with the approaching trough temperatures area-wide are expected to cool several degrees, but more so across inland areas.
Temperatures Thursday are expected to be below average primarily in the mid 60s along the coast, and right around 70 inland.
Temperatures will remain on the cool side with onshore flow for Friday, then a warming trend kicks in by next weekend with offshore pressure gradients getting stronger.
